It works fine under "normal" linux as well, it doesn't really need the vendor/profuct name. However, for an embedded linux, the vendor/ model name was needed, so I added the FIX_INQUIRY. > > Can you provide a usbmon trace or usb-storage verbose debugging log > showing what happens when you don't use FIX_INQUIRY? I added the dump of the hex characters is scsi_scan.c, and as you can see, the name is there but the length (in inq_result[4]) is 0. The solution is maybe to force inq_result[4] to something (31) if 0 in scsi_probe_lun ???
